UNITED STATES PATENT OFFICE.

JAMES H. BEAITY, OF FRANKLIN, PENNSYLVANIA, ASSIGNOR TO SARAH J. BEATTY,J OSIAH B. POOR, AND WILLIAM MGKEE.

IMPROVEMENT IN SUCKER-ROD JOINTS OR COUPLINGS.

Specification forming part of Letters Patent No. 117,371, dated July 25,1871.

To all whom it may concern:

Be it known that I, J AMES H. BEATTY, of Franklin, in the county ofVenango and State of Pennsylvania, have invented a new and usefulImprovement in Sucker-Rod Joint or Goupling; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

rIhe nature of my invention consists of a sucker-rod joint or coupling,with the inner surface of its straps provided with projections adaptedto recesses made in the sucker-rods.

To enable others skilled in the art to make and use my invention, I willproceed to describe more fully its construction and operation.

The accompanying drawing which forms part of my speciiication is avertical and longitudinal section ofthe male part of the coupling-jointand a section of the sucker-rod or pole.

A represents the screw of the coupling. B represents the straps. Crepresents projections on the inner surface of the straps. I) representsthe rivets. E represents the sucker-rod or coupling-pole, which isprovided with recesses or notches which, in form, correspond in vsizeand shape to the projections O on the interior of the straps B. Thecoupling-joint herein described is constructed in all respects in theordinary form, excepting the projections O on the interior ofthe strapsB.

The cheapest method of constructing the hereinbefore-described couplingis casting it of castiron and subsequently annealing it, thereby forminga coupling of malleable iron. The advantage of constructing a couplingor joint for sucker-rods in the manner herein described consists inrelievingthe rivets from transverse strain, giving more metal for theheads of rivets, and holding the rod E more securely in its place.

The advantage of a safe and sure means for securing the sucker or poleto the coupling-joint is a desideratum with operators of oil-wells, forinsecure attachments in the sucker-rod are always a very great source ofannoyance.

Having thus described the nature, construction, and advantages of myimprovement, what I claim as my invention isrIhe straps B provided withprojections O, in combination with rivets D and recesses in the rod E,constructed and arranged as herein described, and for the purpose setforth.

JAMES H. BEATTY.
